Question 1

What is the difference between V2H and V2L?

Accepted Answer

V2H (Vehicle-to-Home) uses a bidirectional charger and transfer switch to power your entire home circuit, including hardwired appliances like your HVAC system. V2L (Vehicle-to-Load) provides a standard 120V outlet directly from the car, powering individual devices you plug in. V2H requires professional installation (~$6,000-9,000); V2L requires no installation.

Question 2

Which EVs support V2H in the US?

Accepted Answer

As of 2024, V2H-capable EVs in the US include: Ford F-150 Lightning (9.6 kW), Rivian R1T and R1S (11.5 kW), GMC Hummer EV (11.5 kW), and Nissan LEAF (6 kW with compatible hardware). V2L vehicles include Hyundai IONIQ 5, Kia EV6, and Kia EV9 (all at 3.6 kW).

Question 3

How long can a Ford F-150 Lightning power a house?

Accepted Answer

A Ford F-150 Lightning Extended Range (131 kWh) can power an average home using essential appliances (refrigerator, lights, phones, router) for approximately 3-4 days. With a full load including HVAC and other high-draw appliances, runtime drops to 8-12 hours.

Question 4

Does using V2H or V2L damage the EV battery?

Accepted Answer

Frequent deep discharging through V2H use can cause additional battery degradation compared to normal driving use. Ford and Rivian recommend keeping a minimum 20% charge reserve. Most manufacturers design V2H systems to stay within safe operating parameters, but extended daily V2H use may accelerate long-term capacity loss.
